I just did the timing belt replacement this weekend.
The Foley video is pretty good, but doesn稚 show you where the crankshaft or camshaft locking pins go. (The access ports)
Tip#1 you are looking for hex head, not Allen head, caps to undo.
Tip#2 on a 2011 engine, the camshaft locking pin access port is just to the left of the oil filter, just above the ports for the auxiliary oil heater. Again, you are looking for a hex head cap to remove.
Tip #3 you will need two replacement copper washers to seal the ports afterwards.
Tip#4 if you need to adjust the timing, the Deutz washer tool is very helpful.
Tip#5 the crankshaft turns two revolutions to the camshaft one, which means that you want to find the camshaft indexhole first. Then, slowly adjust the crankshaft to find the crankshaft index point. Otherwise, you will be hunting for a hole in the camshaft that is 180 degrees away.
For some reason, the timing pins that I bought were oversized, or my camshaft alignment channel was underbored. Either way, it was an interference fit. Does anyone have micrometer readings on the OD of the narrow part of the timing tool?
Adjusting the valve lash made a huge difference in performance for me; no smoke, reduced diesel smell, and noticeably faster idle. YMMV...
All the best,
Peter
